7 Claims.

This invention relates to a spring controlled door hinge construction whereby a swinging door is yieldingly maintained either in open positions or in a closed position.

An object of the invention is to provide improved means for positioning the door per se with relation to its mounting means, thereby causing the door when closed to be more accurately positioned in the door opening, and also determining more precisely the points at which the door will come to a stop when it is swung in either direction to an open position.

Still other objects and advantages reside in the compactness, simplicity and low cost of manufacture of the claimed structures for swingingly supporting a door or other swingable closure element.

The present application is a division of the application for Letters Patent on Closure operat ing device filed February 25, 1935; Ser. No. 8,105 and carries forth the objects outlined therein, and reiterated above.

Other objects, advantages and features of the invention will hereinafter appear.

Referring in detail to the drawings, the door 10, which swings in both directions, is shown in an assembled relation to its lintel 69 and easing member H.

The tubular pivot pin l1 forms the lower hinge of the door. At the upper side of the door a combined hinge plate and gage plate lsprovided, said plate having a downwardly directed hinge pin GI and with screw holes 52. With said hinge plate 60 cooperates a T-shaped socket member 63 having a socket portion 64 to receive said pin and a wing at each side having a screw hole to receive screws directed downwardly into the upper edge of the door. The door. 10 is recessed as indicated in Fig. 1 to receive the socket member 64.

As viewed in Fig. 1, the center of the upper hinge pin BI is located the same distance from the inner (left) end of the gage strip 60 as the center of the lower hinge pin I1 is spaced away from the left side of the base plate 14, which engages the casing. This arrangement provides for mounting the door quickly in a truly vertical position, which is insured by abutting the left end of the gage strip 60 against the upper part of the door casing while the left side of the attached base plate '14 engages the lower portion of the door casing.

The lower pivotal mounting of the door upon the threshold 12 includes the cam device 13, the base plate 14 being interposed between said threshold and cam device. Said base plate is preferably rectangular, and it has a depressed foot portion 15 extending along three sides thereof thus elevating its body portion sufficiently to provide under it a clearance to receive a washer l6 and the peened over lower end of the tubular pivot pin H. A lower housing plate or disc 16 is superimposed upon said base plate and has its upper face engaged by an annular bead or shoulder 20 formed around tubular pin l1 thus clamping together the parts 14 and 16 (see Fig. 4) when the lower end of said pin I 1 is peened over against the lower side of the washer IS.

The cover member is furnished with a central circular rise 25 which cooperates with the top portion of the hollow pin H to form a raceway for the ball bearing members 26, this part of the bearing structure being completed by means of the headed central pivot pin 21, the upper end of which extends loosely thru said cover member and the lower end of which is peened over at 28.

The disc 16 has an upstanding peripheral flange 11, two notches Ha: (see Fig. 3) being made in said flange to aid in forming openings to admit a tool for regulating the screw threaded adjusting means. M

miter member 80 has a downwardly directed peripheral flange 8| which is cut away at 82 and 83 in order to make room for mounting the strap iron 84 shown in detail in Fig. '7. Said 55 strap iron has a hole 847:. to receive the tubular pivot pin H. The lower end of the door is cut away at 85 and the strap iron 84 has an upwardly offset part 86 which underlies and is attached to this part of the door, screw holes 81 being made thru said strap iron to receive screws to attach it to the door. The strap iron 84 may be upwardly directed at 84a into a channel 84:: therefor in the inner edge of the door. Between its base portion 84 and offset portion 86 the strap iron has a riser portion 88 having thru it an aperture 88a wherein is tightly secured one end portion of the guide rod 89. Around said guide rod is slidably fitted the upwardly directed arm 98 of the cam operated slide 9|, the opposite end portion 92 of said slide being downwardly directed to cooperate with the cam block 45.

The slide 9| has an upstruck guide tongue 93 which has a working fit within a slot 94 provided therefor in the strap iron 84. Against the arm 98 of the slide 9| presses one end of a spring 95 which is loosely coiled around the guide rod 89. The opposite end of said spring (see Fig. 1) engages a washer w which is backed by a nut 96 screwed on to said rod.

The top of the cover disc 80 has a radial slot 80s (see Fig. 3) cut thereinto directly above the space thru which the tongue 93 of the slide 9| moves. Said tongue extends thru and somewhat above the guide slot 94 in the strap iron 84, and therefore moves back and forth in said slot 808 also. The opening 83 thru the cover flange 8| is suiflciently wide to admit the strap iron 84 and also to provide a suflicient clearance therebelow to receive with a working fit the slide 9| the body portion of which underlies said strap iron. As shown in Fig. part 8|a: of flange 8| remains intact below parts 84 and 9|, thus providing retaining means for them. At the opposite side of cover plate 80, the strap iron 84 passes thru opening 82 with a close flt.

A cam member, shown as a block 45 is furnished with a symmetrically located bearing aperture 450 (see Fig. 8) whereby it is mounted upon the bearing pin IT with a working fit. Said block has a main central cam face 46. At one side of said cam face is a cam projection 41 and at the other side thereof a like cam projection 48, there being a guiding surface 452: at each side of the main cam face 48 which directs the movement of the cam operated element as it passes from the main cam face 46 to said cam projections. When the guiding surfaces 45.1: are in an abutting relation with element 92 the door is maintained partly open.

The cam block 45 may be regarded as yokeshaped having arms 52 at opposite sides of a recess 5|. Each of said arms has a screw hole extending therethru which opens into said recess. Adjusting screws 53 and 54 are screwed into these holes, the inner ends of said screws acting upon coiled are shown housed in a recess 98 formed by cutting a rectangular piece out of the lower edge of the door and flanking the cut away part by a cover plate 99 attached to each side of the door. Or, if the door is thick enough, a groove may be channeled into the lower edge of the door to receive the parts mentioned, as shown in Fig. 5.

It will be observed that the block 45 is furnished with a series of contiguous peripheral cam faces, thus affording a simple, compact cam structure.

The strap iron 84 is deemed to be a preferred type of elongated member to cooperate with and guide the cam controlling follower 9|, but it is to be understood that other elongated means may be substituted therefor without departing from the spirit of the claimed invention.

In the operation of the device the downwardly directed end flange 92 (see Fig. '7) of the spring opposed slide 9| will continually engage peripheral portions of the adjustably stationary cam block 45. When said slide abuts squarely against the main or central cam face 46 the door will be maintained in its closed position, and if the cam block screws 53 and 54 have been properly adjusted, at such time the door will accurately cooperate with any conventional or other knob-operated or other latching means with which it may be furnished. By gently swinging the door a short distance towards either open position one or the other of the cam faces 453: may be caused to abut squarely against the slide flange 92 thus holding the door slightly open. If the door be swung widely open in either direction the flange 92 will pass over the projection 45 or 48 of the block and will be caused to engage the block at two points, namely, the projection thus passed over and the extremity of the arm 52 at that side of the block, and the block will thereupon cooperate with the slide to maintain the door wide open. One of the side open positions of the door is indicated by dotted lines in Fig. 3.

The parts may be so adjusted that when the door is in either of the slightly opened positions already referred to, one or the other of the adjusting screws (53 or 54) will come opposite to one of the notches 11x, as shown in Fig. 6. This will afford ready access to the screw selected, which may then be unscrewed to the desired extent, the position of the door thereupon being reversed so that the other screw may be screwed in sufficiently to take up the lost motion which would otherwise result.

What is claimed is:

1. In a device for controlling the movements of a swinging structure, a base having a pivot upstanding therefrom, said pivot having an annular bearing surface at its upper end, a ball bearing mounted upon said bearing surface, a cover member-adaptedfer-attaclnnentto a swin tiea stud H (see 4) having a headed contract- -tureasaid member having a rise cooperating with ed downward extension I32 whereby said stud is secured to plates 14 and I6 and at the same time aids in securing said plates to each other.

The adjusting screws 53 and 54 are accessible for adjustment only when the door is in partly open positions, one of which is shown in Fig. 6, where the flange opening or cut-away part 82 and notch 112: are seen in register with each other. Therefore unauthorized persons cannot tamper with said screws while the door is locked in a closed position.
